When Glee wants to take over, they take over! Check out this killer performance of “Don’t Stop Believin” by the cast of Glee on The X Factor!

Glee is beloved all over the world, which was made abundantly clear when the cast rocked the stage on the UK hit show The X Factor Nov. 30. Don’t worry — Sue Sylvester and Mr. Schuester were there, too!

After a hilarious introductory video starring Sue and Will, the Glee cast sang the song that launched the hottest show on TV: Journey’s “Don’t Stop Believin’.” Plus, we got to hear solos from not onlyLea Michele and Cory Monteith, but from Chord Overstreet, Naya Rivera, Mark Salling and Kevin McHale.

The best part? Amber Riley, who was once rejected when she auditioned for American Idol, strolled up to Simon Cowell and sang right up in his face.The cast of Glee is scheduled to tour the UK this summer.
